Transmission and Transfer Case are two seperate things.
Without 4WD you won't have a transfer case or front differential - instead the transmission goes directly to the rear differential via the driveshaft.
The transfer case connects to the transmission, one shaft goes to the front diff, the other goes to the rear diff.
4 seperate items. 2 are joined together...the transmission and transfer case...and they have their own fluid.
If you don't know, don't do it - take it to a shop, have them teach you, then you can do it on your own.
Don't walk in blind, that's how bad things happen!
